COMPOSITE PROFILE AND INSULATING STRIP THEREFOR - An insulating strip for a composite profile for window-, door- and facade elements includes an insulating strip body that extends in a longitudinal direction and has at least two longitudinal edges separated from each other in a transverse direction. The longitudinal edges are designed for a shear-resistant connection with profile parts of the composite profile. The insulating strip body has openings passing through one or more walls of the insulating strip body in a height direction. The openings are separated from each other by strips in the longitudinal direction, which strips are shaped like ladder rungs. The insulating strip body is formed to receive a clipped-on covering profile that covers the openings.

Blank for Spacer for Insulating Window Unit, Spacer for Insulating Window Unit, Insulating Window Unit and Method For Manufacturing a Spacer - A blank for a spacer for an insulating window unit preferably includes a core made of a metal sheet, e.g., stainless steel, and a coating made of a synthetic material, e.g., polypropylene. The coating preferably has a thickness in the range of 0.02 to 0.2 mm and the core preferably has a thickness in the range of 0.05 to 2 mm, more preferably between 0.1 to 0.3 mm. Further, the insulating window unit preferably includes at least two glass windows, which extend in parallel and are spaced a first distance from each other. The first distance preferably is maintained by the above-mentioned spacer, which spacer is adhered to the glass windows using an adhesive or a sealing compound.

REINFORCED PLASTIC PROFILE FOR WINDOW, DOOR AND FACADE ELEMENTS - A reinforced plastic profile for window, door and facade elements has a plastic profile body, which extends in a longitudinal direction, and at least one reinforcement element. The plastic profile body includes at least one receptacle guide extending in the longitudinal direction. The at least one reinforcement element is connected with the plastic profile body in a longitudinally-fixed manner by foam-filling the receptacle guide with the reinforcement element positioned therein. As a result the reinforcement element is precisely positioned relative to the outer geometry of the plastic profile body.

PLASTIC PROFILE FOR WINDOW, DOOR AND FACADE ELEMENTS - A plastic profile for window, door and facade elements includes a plastic profile body, which extends in a longitudinal direction (z), and at least one outer side, which is located outside in a transverse direction (x) perpendicular to the longitudinal direction (z) as viewed in a cross-section (x-y) perpendicular to the longitudinal direction (z). The outer side includes two roll-in protrusions configured such that a reinforcement element is connectable with the plastic profile body by a rolled-in connection. The reinforcement element has at least one of a hollow profile, a partially-open profile and a receptacle portion configured to accommodate a corner connector, wherein at least one of the hollow profile, the partially-open profile and the receptacle portion is disposed between the roll-in protrusions in the rolled-in state.

INSULATING STRIP FOR SUPPORTING A COMPOSITE STRUCTURE - An insulating strip is configured to support two profiles or frames in a spaced relationship. The insulating strip includes a body extending in a longitudinal direction and has at least first and second longitudinal edges. The longitudinal edges are configured to be connected with the respective frames or profiles in a shear-resistant manner. Openings penetrate through one or more walls of the body and one or more struts separate the openings from each other in the longitudinal direction of the body. The body further comprises at least one attachment structure configured to retain a covering profile configured to cover the openings. The covering profile may be integral with the insulating strip body or may be a separate part. A composite structural unit comprises two frames supported in a spaced relationship by such an insulating strip.

SPACER PROFILE HAVING A REINFORMENT LAYER - A spacer profile for use as a spacer frame in an insulating window unit includes a profile body made of a synthetic material and having an inner wall, an outer wall and sidewalls, which define a chamber for hygroscopic material. A diffusion barrier layer is made of a first metal material and has a first tensile strength and a first thickness. The diffusion barrier layer is disposed at least on or in the outer wall and at least a portion of the sidewalls. A reinforcement layer is made of a second metallic material and has a second tensile strength and a second thickness. The reinforcement layer is formed in the inner wall or on the side of the inner wall, which is directed towards the chamber. The multiplication product of the second thickness and the second tensile strength is preferably greater than the multiplication product of the first thickness and the first tensile strength.

PUMP FOR CONVEYING A CRYOGENIC FLUID - A pump for conveying a cryogenic fluid from a tank into a container which is under a higher pressure. The pump includes a cylinder having a piston which defines a low-temperature chamber and a high-temperature chamber in the cylinder such that during a first stroke movement of the piston, the volume of the low-temperature chamber decreases and the volume of the high-temperature chamber increases correspondingly, and during a second stroke movement of the piston which runs in the opposite direction of the first stroke movement, the volume of the high-temperature chamber decreases and the volume of the low-temperature chamber increases correspondingly.
